Time Period Percentage of MDQ

----------- -----------------


November 1 through March 31 10%

April 1 through April 30 15%


(b) For the period of May 1 through October 31, a

Shipper's IQ varies by time period and its April 30 DSS storage

balance (the April 30 storage balance is assumed to be zero until

Natural notifies Shipper of the balance) and is determined by the



IQ = (MSV - April 30 storage balance)(MDQ)(X)




where X varies by time period as follows:


May 1 through July 31 30%

August 1 through October 31 40%


Notwithstanding the foregoing, Natural will post on the

Informational Postings portion of its Interactive Website no later

than March 31 of a year (except that for the Year 2001 the posting

will be made by June 4) if operational conditions on its system

will permit X to be increased from 30% up to a higher level not to

exceed 40% over all or any portion of the period from May 1

through July 31 of that year (June 4 through July 31 for 2001).

The posting may specify different values of X for different time

periods between May 1 and July 31 (June 4 and July 31 for 2001),

within the 30% to 40% range.


(c) (1) Subject to subsection (2) below, a Shipper's

firm injection rights on any day shall be further limited as

follows: fifty percent (50%) of a Shipper's IQ shall be available

for injection from sources on the Amarillo Line and fifty percent

(50%) of a Shipper's IQ shall be available for injection from

sources on the Gulf Coast Line. Gas which a Shipper seeks to have

scheduled and Natural is able to schedule on either line in excess

of the resulting daily firm injection volume, or in excess of the

storage balance limits defined in subsection (3) below, shall be

treated as authorized overrun, with the same priority as other

authorized overrun injections under Section 5.5(b) of this Rate

Schedule DSS.
